How do we know that Jesus is the perfect sacrifice?

The Old Testament required that sacrifices be without blemish, as outlined in Leviticus. Jesus, as the ultimate sacrifice, met this criterion perfectly. He lived a sinless life, fulfilling the law's demands entirely. Hebrews 4:15 states that He was tempted in all ways, yet without sin. This perfection allows His sacrifice to be accepted by God, satisfying the wrath against sin for His elect. Moreover, Christ's death and resurrection affirm the sufficiency of His atonement for all who believe.
